The stingray, which spends much of their time partially buried on the ocean floor, uses its paired pectoral fins to stabilize their movement through the water and sweep away sandy foreign particles from its surface. A research team, affiliated with UNIST has drawn inspiration from such natural processes to create innovative solutions to prevent the adhesion of contaminants to device surfaces.
